Description of the Invention (l) [Technical Background of the Invention] / ¾ y The present invention relates to the removal of adhesion from substrates such as semiconductor wafers or LCDs by centrifugation Liquid, and spin dryer and substrate drying method for substrate surface. ^ In the wafer manufacturing process for manufacturing semiconductor devices, the wafers are chemically cleaned to purify the surface of the semiconductor wafers, and then dried after being washed with water. In the wafer drying process, for example, U.S. Patent No. 5,4 35,075, Japanese Utility Model Publication No. 63-180925, Japanese Patent Application Laid-Open No. 7-17651, and Japanese Patent Application Laid-Open No. 6-9 7 1 4 8 are used. It is described in the bulletin and the like. However, in U.S. Patent No. 5,4 3,5,07,5, in order to allow the drying air to fully and uniformly contact each wafer, the drying air is effectively introduced, and the effectively introduced air must be distributed. In each of the two spaces between the wafers. In addition, particles generated by dust generation or charging from a rotary drive source or peripheral machinery may be mixed into the drying air, and particles and the like may adhere to the wafer during the drying process, causing problems such as contamination. In addition, due to the back-flow to the air processing chamber side of the exhaust gas, particle removal is attached to the wafer. The device described in Shikai Sho No. 63-180925 is a pair of box-shaped box skeletons that can swing freely on a pair of frame walls that are erected on the rotating skull, and at the same time, the two box frames can be separated or approached. . According to this device, after the magazine housing most wafers is put into the magazine holder, the two magazine holders are separated. When the rotating body is subsequently rotated, the cassette frame forms a horizontal state so that the adhesion liquid is centrifuged from the wafer. However, this conventional technique is a structure in which wafers and boxes that are cleaned and processed are put into a box rack at the same time, so its possession capacity (please read the note on the back 3, write this page) al'ii.

Description of the invention (2) The large size leads to the enlargement of the device. In addition, not only the wafers, but also the magazines are also the subject of drying, so there is a problem that the time required for drying increases. In addition, since the cassette is inserted into the cassette frame, a turbulent flow M is caused to supply the air for drying, thereby reducing the drying efficiency. In addition, the turbulent flow of drying air may cause particles to adhere to the wafer, which may cause contamination. The device described in Japanese Patent Application Laid-Open No. 7-1765 1 2 has a lotus-shaped arm for holding a wafer sent by a lotus on a mounting table (box), and a box shape placed in the mounting table (box). cradle. The shaker includes a member that holds the mounting table below the wafer and a holding member that holds the periphery at the center of the wafer. This device has a structure in which the above-mentioned mounting table is housed in a box-shaped cradle in place of an M-replacement box, and therefore, it has a small occupation volume and a small-sized device. However, this conventional device is formed into a box-type cradle. Therefore, the supplied drying air may cause turbulence when passing through the cradle, thereby reducing drying efficiency. In addition, the turbulent flow of drying air may cause particles to easily adhere to the wafer, which may cause contamination. The device described in Japanese Patent Application Laid-Open No. 6-9 7 1 4 8 includes a pair of rocking blues which can be tilted and moved freely relative to each other, and a horizontal holding mechanism for horizontally holding such cradles. In addition, the two sides of the cradle are equipped with a mechanism that can push and hold the periphery of the wafer to prevent the wafer from falling off during rotation. However, the wafer pushing mechanism of the conventional device is quite complicated in structure. And because the crystal picture is held by the elastic force of the spring, the contact area between the holding member and the crystal circle is increased, and foreign matter is likely to adhere to the wafer, which may cause contamination. In addition, if the pushing force is too large, the wafer may be deformed. This paper size applies the Chinese National Standard (CNS) A4 specification (210 X 297 mm) _ 5-: 4〇758758 A7 B7 V. Description of the invention (3) Furthermore, the conventional rotary dryer must be relieved due to high-speed rotation. Damage caused by wafer impact. [Summary of the Invention] The object of the present invention is to provide an efficient use of drying air * and to minimize the contact area between the substrate and the holding portion, and to prevent the adhesion of dust particles and the occurrence of contamination, and to improve accuracy and productivity.

The temporary plate 17 is formed in a semicircular arc shape substantially the same as the wafer W, and protrudes from the supporting frame 14 toward the center of rotation. Approximately half of the area of the wafer W held in the cradles 10 a and 1 Ob is covered by the temporary plate 17. The temporary plate 17 can rectify the air flowing on the wafer W held on the upper end portion side of the cradles 10a and 10b, and the upper end portion wafer W can be prevented from being damaged by the turbulent flow. The Consumer Cooperatives of the Central Bureau of Standards of the Ministry of Economic Affairs printed the structure in which the upper mechanism of the rotating body 2 is opened on both sides and in the upper part of the radius of rotation as described above. Taken), the air introduced from above is dispersed from the central portion of the rotating body 2 to the side wall 11, the rectifying plate 16, the cradle 10 a, and the gap between the wall portion 14 a of the LOb and the gap between the wafers W. Therefore, it is possible to efficiently discharge the water droplets adhering to the wafer W by the centrifugal separation. As shown in Fig. 5 and Fig. 8, the bottom surface portion 30b of the processing container 30 has a downward gradient in the radial direction toward the outer exhaust vent 30c, and also has a downward gradient in the rotation direction. By forming the bottom surface portion 30b as described above, the liquid droplets on the wafer W can be quickly separated from the processing container 30 by centrifugation. Secondly, referring to Figures 10_ ~ 18, the supporting frame 14 and the blueprint paper size are applicable to Chinese National Standard (CNS) A4 (210X297 mm) -16-A7 B7 V. Description of Invention (14) Central Standard of the Ministry of Economic Affairs Bureau employees' consumer cooperatives printed 10a and 10b as follows. Essentially, the left and right symmetrical support frames 14 are arranged with the same 2 ，, so the following description of M is the support frame 1 4 on the M side. The supporting frame 14 includes a supporting base 15 with a supporting base 21, a pair of holding portions 18, two first holding rods 19, two second holding rods 20, and a pair of guide shafts 22. The pair of holding portions 18 are provided opposite each other to support the upper side wall of the frame 14 and form two or five equally spaced grooves 18a on opposite sides. A peripheral edge portion of the largest diameter portion of the wafer W is inserted into the grooves 18a, so that the wafer W can be stably held in the support frame 14 without vibration. The lower support body 15¾ is composed of a first holding rod 19, a second holding rod 20, and a supporting base 21. The first holding rod 19 is held at two positions that are offset from the lowermost end of the wafer W and held. The second holding rod 20 is formed to hold the wafer W at a position outside the first holding rod 19. The first holding rod 19 and the second holding rod 20 are formed with 25 grooves 19a and 20a, respectively. In addition, the holding portion 18, the first holding rod 19, and the second holding rod 20 are made of a material having drug resistance and resistance, such as ρ τ FE (polytetrafluoroethylene) or PFA (tetrafluoroethylene fluoroalkyl ethylene). Ether copolymer), quartz or PEEK (polyketide ether). The support frame 14 and the support base 21 are formed of an aluminum alloy member whose surface is hardened, and the surface is impregnated with a fluororesin. As described above, the support frame 14 and the support base 21 are formed by the aluminum alloy member, and the surface is impregnated with the fluororesin, thereby reducing the weight of the lower support and increasing the life span. In addition, it may be possible to form at least Κ aluminum alloy members to support the base 2 1 Please read the back © Note # Binding This paper size applies to Chinese National Standard (CNS) A4 (210 × 297 mm) -17-402758 A7 _____ B7_______ 5. In the description of the invention (15), the surface is impregnated with fluororesin. When the support base 21 is formed only by an aluminum alloy member after electrolytic honing, the stainless steel member after electrolytic honing can be used for the support frame 14. Since the first and second holding rods 19 and 20 can support the wafer W at the M4 point, the lower side of the wafer W can be held stably. In addition, without holding the holding rods 19, 20, the droplets can naturally fall from the lowermost end portion of the wafer W to form a good droplet removal. At this time, the holding groove 19a provided in the first holding rod 19 is formed as shown in FIG. The holding groove 20a provided in the second holding rod 20 is a V-shaped groove portion 2b of the M-shaped cross section as shown in FIG. 20b, and an open end from the V-shaped groove portion 20b. The expansion groove portion 2 0 c is gradually inclined toward the expansion direction. Further, the holding groove 18a provided in the holding portion 18 is formed as shown in FIG. 15C with a groove base portion 1 8b having a thickness larger than the thickness of the wafer W, and is expanded from the open end of the groove base portion 18b. The open groove portion 18 c inclined in the opening direction has a substantially V-shaped cross section. As described above, the holding groove 19 a of the first holding rod 19 is formed into a V-shaped cross-section, which can support the lower end portion of the wafer W, and the WV Yu plough groove portion 20 b and the expanded groove portion 20 c constitute The holding groove 2 0 a of the second holding rod 20 is used to support the upper position of the portion supported by the first holding rod 19 by the V-shaped groove, and the lateral direction of the wafer W can be restricted by expanding the groove portion 20 c. mobile. Further, the holding grooves 18a provided in the holding portion 18 are formed in a V-shaped cross section, which can maintain the positions of both sides of the center portion of the wafer W in a state where the lateral movement is restricted. Therefore, the contact with the wafer W can be minimized, and the wafer W can be kept in a stable state.

In addition, the processing container is provided with an air inlet at a position relative to the center of rotation of the rotating body, and at the same time, an exhaust port extending from the bottom to at least the height of the rotating body is provided on a part of the side wall of the processing container, thereby enabling the Drying air is introduced into the center of the body and uniformly flows into the gap between the substrates and the substrates, and the droplets centrifuged on the substrate can be discharged to the exhaust port side. The lower supporting body on the lower side of the holding substrate is formed to be able to freely rise and fall relative to the supporting frame, thereby raising the lower supporting body to transfer the substrate. When the lower supporting body is lowered, the lower supporting frame and the supporting frame can be used. The holding portion of the body holds the substrate. Therefore, a simple structure can be formed. In addition, the contact area with the substrate can be reduced, and at the same time, the substrate can be reliably transferred and maintained. Therefore, it is possible to prevent particle spatter and contamination and improve accuracy. In addition, the upper support body on the upper side of the substrate can be fixedly held, whereby the upper support body can be fixed to make the holding of the substrate more stable during rotation. In addition, since the first holding rods at the two lower portions offset from the lowermost end portion of the substrate and the second holding rods at the two positions outside the first holding rods are configured as holding portions of the lower support, it is effective. While the water droplets adhering to the substrate are eliminated, the substrate can be kept in a more stable state. In addition, the first holding rod on the lower end side has a V-shaped groove to support the upper position of the lower end of the substrate. At the same time, the groove can be expanded (please read the precautions on the back before filling this page) -Binding-Stitching. The paper size is applicable to China National Standard (CNS) A4 specification (210X 297 mm) -29-402758 A7 B7 V. Description of the invention (27) The direction of the board is shifted as much as possible The contact with the substrate can more reliably prevent the occurrence of particles or contamination. In addition, at least the supporting base is formed of an aluminum alloy member, and the surface of the aluminum alloy member is impregnated with fluororesin for a while, so that the lower support frame can be made lighter and more resistant to corrosion. As a result, the life of the device can be extended. The mobile device is used to form a relatively movable support device, and the switch device is used to form a cover that can freely open and close the processing chamber containing the rotating body and the support device. When the M mobile device is relatively moved to support the device, the switch device is used to form a freely opened and closed cover. Therefore, the relative movement of the supporting device and the opening and closing operation of the cover can be performed at the same time, so the preparation time before and after the drying process can be shortened, and the yield can be improved. In addition, the time from the cleaning process to the spin-drying can be shortened to prevent the occurrence of water stains on the substrate surface. Furthermore, by rotating the rotating body at a low speed during start-up, and then rotating at a high speed, the impact on the substrate during start-up can be mitigated and damage to the substrate can be reduced, thereby improving its accuracy.
